* AKPublic.Verify: Return an error if a provided PCR of the correct
digest was not included in the quote.
* AKPublic.VerifyAll: Implement VerifyAll method, which can cross-check
that provided PCRs were covered by quotes across PCR banks.
* PCR.QuoteVerified(): Introduce getter method to expose whether a
PCR value was covered during quote verification.
As part of the Boothole fixes, shim has introduced an
SBAT feature https://github.com/rhboot/shim/blob/main/SBAT.md.
SBAT configuration is configured to log to PCR7 using
EV_EFI_VARIABLE_AUTHORITY.
493bd940e5/mok.c (L228-L247)
This causes issue with ParseUEFIVariableAuthority, as
it asssumes that an event with type EV_EFI_VARIABLE_AUTHORITY
can be parsed as EFI_SIGNATURE_DATA, per section 3.3.4.8
of the TCG PC Client Platform Firmware Profile Specification.
